Automatic self contained collapsible traffic barrier bollard system and method of installation

Abstract

A collapsible traffic barrier system is disclosed which includes a steel vault having a top, a bottom, two ends, an approach side and a shoulder side. The top may be treated with anti-skid material. A rod is rotatably mounted to support members inside the vault, wherein the rod extends across the vault from end to end. A plurality of bollards are coupled to the rod substantially near the first end thereof, whereby rotation of the rod rotates the bollards so as to extend the second ends of the bollards above the vault in a vertical direction, or raised position. An actuator having a first end anchored within the vault and a second end is coupled to the rod by means of an arm. The actuator is a worm-drive mechanism disposed for rotating the rod. A stop is anchored to the bottom of the vault for engaging the first ends of the bollards when the bollards are in the raised position.

Description

[0001] This is a continuation of Provisional Application No. 60 / 404,272, filed Aug. 19, 2002 by the same inventors hereof.[0002] 1. Field of the Invention[0003] The present invention relates generally to an automatic collapsible self-contained, below-grade traffic barrier bollard system which can be installed with a minimum amount of excavation and minimum on-site construction. The system may be installed into a foundation perimeter and features a novel and unique rapid deployment system.[0004] 2. Description of the Prior Art[0005] With the recent terrorist's attacks and threats of further attacks, security has become of utmost concern to businesses, local, state and federal governments and especially the military. Many security devices are currently available, especially traffic barricades. Such traffic barricades come in a wide variety of types adapted for general and specific purposes. However, the present invention relates specifically to collapsible road traffic barriers and ba...

AI Technical Summary

Problems solved by technology

Additionally, prior techniques do not suggest the present inventive combination of component elements as disclosed and claimed herein.

However, many require extensive excavation work, which often results in serious access problems due to the extensive time required for construction and installation.

Although there have been many inventions related to traffic barrier bollard systems, none of the inventions have become sufficiently compact, low cost, and reliable enough to become commonly used.
